| Abstract: |
| 室内试验表明:灭幼脲1、2、3号和除虫脲1号对淡色库蚊幼虫有很高毒效;灭幼脲2、3号对三带喙库蚊幼虫亦有较高毒效;除虫脲1号对白纹伊蚊幼虫效果也较好。几种药对两种库蚊幼虫皆有较长的残效。对两种库蚊蛹有一定的杀灭效果。灭幼脲2号、3号和除虫脲1号对小白鼠无毒。除虫脲1号对鱼和罗氏沼虾安全。在稻田杀灭三带喙库蚊幼虫试验中,用除虫脲1号和灭幼脲2号投药九天后效果基本保持不变。 |

| A comparison study on the efficiency of TH6040, TH6038, Ton-Urea No3[N-(4-chloropheuyl-N2-chlorobenzoyl)urea] and TH6040-Tanghan on killing laryae of mosquitoes was carried out, It was found that ① all these insect orowth inhibitors gave satisfactory killing effect on larvae of C.pipiens pallens,②TH6038 and Tong-Urea No3 showed high polsoness In killing Tritaeniorhynchus and③TH6040-Tangshan killed larvae of Aedes obbopictus perfectly, the killing effect on Culex of some insect growth inhibitors persisted for at least 9 days(observation period).TH6038 and Tong-Ured No3 were found to be nontoxic to mice and TH6040 to fish and prawn. |
